Thermoelectric Irrigation ModuleSalman Mohagheghi and Jamison OlstenSummary: A control module that activate sprinkler bases on ambient temperature and soil
temperature and humidity.Description: This invention is of a module that can be mounted on or added to sprinkler heads
or other irrigation outlets in order to open or close the valve remotely and based on the ambient
temperature, soil temperature and soil humidity. It is triggered based on the humidity of the soil
without a need for additional humidity sensors. Deployment of this module can help save
unnecessary water usage, and allows for implementing a customized, intelligent and
decentralized water irrigation system. Using the proposed modules makes it possible for
individual sprinkler heads or other irrigation outlets to be turned on and off based on localized
ambient temperature as well as soil temperature and humidity without a need for installing
additional sensors. The module can be tuned prior to installation so that it triggers based on user
preferences for individual watering zones.Main Advantages of this Invention
 As opposed to similar products in the market, the unit is self-powered and does not need
electricity, or on-board battery units, or solar panels.
 The module does not require maintenance, and can be installed with minimum effort.
 Reduces water use. Allows for implementing a customized, intelligent and decentralized
water irrigation system.Potential Areas of Application
 Residential and commercial irrigation
 Agricultural irrigation
 Green housesID number: 16037Intel ectual Property Status: US provisional patent filed.Opportunity: We are seeking an exclusive or non-exclusive licensee for implementation of this
technology.
